The child looks pale and ill. He may experience dizziness and has recurring headaches. It is possible he may be suffering from migraine headaches. Although they are often hard to diagnose, migraine headaches don't affect adults only.

[W. Donald Shields] has explored the occurrence of migraines in children but cautions that information is scarce and inconclusive. Evidence seems to indicate that migraines have a genetic link and thus can be inherited.

Shields agrees with the genetic theory, but has different figures. "Obviously there is a genetic connection because about two-thirds of the children who have migraines have parents who had migraines. I don't think anybody understands what causes it," said Shields.
